No, it’s nothing like a horoscope. It’s not the best we can do as far as empirically validated personality tests but it’s results are, to use the psychometric terms, reliable and valid. One test will agree with another and the scores are useful for prediction.
Comparison with the best in class personality test.
> The big five versus the big four: the relationship between the Myers-Briggs Type Indicator (MBTI) and NEO-PI five factor model of personality
> Abstract
This study sets out examine the relationship between two personality measures—most popularly used measure in the consultancy and training world (the Myers-Briggs Type Indicator) and one of the most heavily used measures in the academic research area on personality (the five factor NEO-PI). One hundred and sixty adults completed the NEO-PI and the MBTI. The NEO-PI Agreeableness score was correlated only with the thinking-feeling (T-F) dimension; the NEO-PI Conscientiousness score was correlated with both thinking-feeling and judging-perceiving (J-P) dimension; the NEO-PI Extraversion score was strongly correlated with the extraversion-introversion (E-I) dimensions, while the Neuroticism score from the NEO-PI was not related to any MBTI subscale score. The openness dimension was correlated with all four especially sensing-intuitive. These results were related to two other similar comparative studies. Results are discussed in terms of recent criticisms of the MBTI.
